using buttons - attaching Command objects?

[Magnus]

Hi,

is the following possible:

1) Having one ClickHandler for several Buttons.

2) Associating a Command object to each Button.

3) Knowing which Command object belongs to the clicked Button?

I want something like this:

Button btn_1 = new Button ("B1");
Button btn_2 = new Button ("B2");
Button btn_3 = new Button ("B3");
Command cmd_1 = new Command(1);
Command cmd_2 = new Command(2);
Command cmd_3 = new Command(3);
...
// in ClickHandler:

 public void onClick (ClickEvent e)
 {
  Command c = getCommandForButtonFromClickEvent(e);
 }

Thanks
Magnus
